Heat
Staying in extremely hot temperature, such as in baths, sun burns, or hot tubs can cause your blood vessels to dilate. This increases the absorption of insulin faster and could result in low blood sugar levels.
Losing Sleep
Studies show that constantly not getting enough sleep in the night can result in some insulin resistance.
Coffee
Coffee contains high levels of caffeine which causes high or low blood sugar levels. The effects of coffee on your blood sugar level depends on your sensitivity to caffeine.
The “Dawn Phenomenon”
You may experience sugar surges early on in the early hours of the day, even if you don’t have diabetes. However, for people with type 1 diabetes, this may mean a spike in blood sugar levels.
